Dr. Van Halbach is a leader in neurointerventional radiology, which uses minimally invasive procedures to diagnose and treat disorders of the brain and spine. He specializes in treating hemorrhagic and ischemic stroke, dural fistulas (abnormal blood vessel connections in the membrane covering the brain and spinal cord) and cerebrovascular malformations (abnormal blood vessels in the brain). Halbach earned his medical degree at the University of California, Los Angeles. He completed his residency and a fellowship at Ronald Reagan UCLA Medical Center. Halbach has served as president of the American Society of Interventional and Therapeutic Neuroradiology (now the Society of NeuroInterventional Surgery), and has held numerous other positions in national and international societies. He has coauthored more than 200 peer-reviewed articles. The UCSF Department of Radiology and Biomedical Imaging honored him with its outstanding teaching award in 1999. Dr. Halbach is highly rated in 8 conditions, according to our data. His clinical expertise encompasses Arteriovenous Malformation, Vein of Galen Aneurysm, Cerebral Arteriovenous Malformation, Thrombectomy, and Angioplasty.

Dr. Nicholas Fidelman is a radiologist who specializes in caring for patients with liver cancer, metastatic colorectal cancer and neuroendocrine tumors. He has expertise in liver-directed therapy, a treatment that directly targets cancer in the liver. He also is experienced in treating portal hypertension (high blood pressure in the veins connecting the digestive organs to the liver), biliary disorders (which affect the bile ducts and gallbladder), urinary system disorders, and in performing dialysis interventions (minimally invasive procedures to restore blood flow in vessels used for dialysis). Fidelman's research focuses on clinical trials investigating novel treatments for liver cancer, outcomes of commonly performed procedures in interventional radiology, and on improving the safety and efficacy of image-guided treatments. Fidelman earned his medical degree from UCSF, where he also completed a residency in radiology and a fellowship in vascular and interventional radiology. Dr. Fidelman is highly rated in 13 conditions, according to our data. His clinical expertise encompasses Liver Cancer, Ascites, Fibrolamellar Carcinoma, Liver Embolization, and Gastrostomy.
